Overview
The DRV8316CRRGFR is a fully integrated three-phase motor driver from Texas Instruments, designed for brushless DC (BLDC) and stepper motors. It operates with a supply voltage range of 4.5V to 35V and delivers an 8A peak output current. The device features low on-resistance power MOSFETs and supports PWM input interfaces. Packaged in a 40-pin VQFN (7x5mm) with an exposed pad, it integrates control logic and power stages into a single compact solution suitable for space-constrained applications.
Feature Summary
- Fully integrated three-phase gate driver with embedded power MOSFETs
- Supports PWM input interface for speed and direction control
- Compact surface-mount packaging with thermal dissipation pad
Applications
- Brushless DC (BLDC) motor drives
- Stepper motor control systems
- General-purpose multi-phase motor applications
Procurement Notes
Verify the specific suffix 'C' against the official datasheet to confirm temperature grade or variant specifications. Confirm package dimensions match the 40-VQFN (7x5) footprint. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference the manufacturer part number directly with the component marking to avoid counterfeit risks.
Selection Notes
Select this component when a compact, integrated solution for three-phase motor control is required without external discrete drivers. It is suitable for designs needing high peak current capability within a small form factor. Consider the operating voltage range and thermal requirements relative to the PCB layout capabilities for the exposed pad.
Part Context
This part belongs to the DRV8316 series of motor drivers. It serves as a complete power stage solution, combining logic control with high-side and low-side MOSFETs. The series targets applications requiring efficient drive for BLDC and stepper motors in consumer and industrial electronics.
Replacement Considerations
Consult the official TI selection guide for direct pin-compatible alternatives within the DRV8316 family. Verify electrical parameters such as RDS(on) and operating voltage ranges before substituting with other manufacturers' parts.
